The focus confirmation in using manual lenses on the F4s I had seemed rather loose and inexact. I ended up returning the camera because it had LCD bleed, and I am thinking of getting another F4s, but I want to be certain that it offers good focus confirmation with manual focus lenses. Again, it was difficult to get the confirmation dot to be steady, and thus the readout would keep toggling between the dot and the arrow indicators. Did I have a bad F4s or is this just the way the F4s is? In comparison, I had no problem getting a confirmation dot in my manual focusing with the N90s. I like having the aperture displayed in the finder, and thus I would prefer having the F4s over the N90s...but only if I can regularly achieve proper focus manually.
